There is a lot of loneliness in the world. Americans don't go to community dances anymore. Most people don't have a church "family". Everyone stares at their cell phones instead of engaging in conversations with strangers. We like the political comments on Facebook we agree with, and ignore or argumentatively comment on the statements we disagree with. In our media overwhelmed society we listen to what we want to hear, and flee the uncomfortable situations, like meeting new people with different ideas.
I have no solution, no recommendation. I get lonely too. Well, perhaps the solution is to get yourself into uncomfortable social situations, like actually come rock climbing sometime, or go to church when you are invited, or speaking to myself, actually get out on that dance floor.
